Keystone's website will list models and floor plans that offer a "full size", 60x80 queen mattress. Find a floor plan you like and read the Keystone's description. Usually, it will be mention if the coach has a 60x80 queen. This is something that a manufacturer will broadcast to create a "want" among prospective buyers. On the other hand, a short rv queen (60×74) model may not list the mattress size as the manufacturer will emphasis other notable features. It's all marketing in the end. If you find a unit that does not include mattress dimensions, you can call Keystone customer service to verify what is standard. The Bullet line generally offers a RV queen where as the Passports offer a residential queen.
